SEIVI IDRY OR SEMIPLASTIC BRICK MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 636,095, dated October31, 1899. Application filedDecember 28, 1898. Serial No. 700,521. (Nomodel.)

To all whom it may concern.-

Be it known that I, ADAM ADAMS, a subject of the Queen of Great Britain,residing at Old Hetton, Peterborough, in thecounty of Huntingdon,England, have invented an Improved Semidry or Semiplastic Brick MakingMachine, of which the following is a full, clear, and exact description,and for which I have made application for British Patent No.l2,851,dated the 8th of June, 1898.

I provide a circular drum or cy1inder,which revolves continuously andcontains the molds in which the material is to be pressed. There is abottom head or plunger to each mold or set of molds, and these receivetheir motion by means of a fixed cam, around which they revolve with thecylinder. 'The top heads or plungers, each or each pair of which entersevery other mold or pair of molds once during a revolution, travel withthe cylinder while they give their pressures, after which they arecarried back to their former position automatically. The motion of thetop heads or plungers, apart from their circular movement, is arrangedto be given by eccentrics driven at the correct speed and in the rightdirection in relation to the cylinder and transmitted throughtoggle-levers or other mechanical arrangement. Havingreceived the properpres sure and shape, the bricks are pushed out of the molds by thebottom heads and are carried on to the table or belt by a rocking arm orsimilar contrivance. The heads, both top and bottom, are steam-heated.

This machine does not waste a single portion of its stroke, and so canturn out twice the usual number of bricks and still remain for a longerperiod on each one with a much slower movement of working parts.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is an elevation of the machine, partly in section. Fig. 2 is aplan of the same in semisection. Figs. 3, 4, 5, and 6 are diagrammaticalelevations showing the motions and positions of the various parts. Fig.7 is an elevation, on areduced scale, of the machine with driving-gear,one side of frame, and one pair of eccentrics removed, showing thesegment-retaining straps and also arrangement for regulation of feed.Fig. 8 is an elevation, and Fig. 9 a plan, of one pair of molds. Fi

10 is a front elevation, and Fig. 11 a side elevation, of bottomplunger. Fig. 12 is a front elevation, and Fig. 13 a side'elevation, oftop plunger. Fig. 14 is a front elevation of-catch on eccentric-arm andFig.15,a side elevation, partly in section, drawn on the line 15 15 ofFig. 14. Fig. 16 is a section of a portion of cylinder-frame, showingone of the catches; and Fig. 17 is a plan of same. Fig. 18 is a frontelevation, and Fig. 19 a side elevation, of rocking lever for operatingthe pusher.

A is the cylinder, in which are placed the molds B at regular intervalsaround the circumference either singly or in pairs. The machine ispreferably made, as shown in the drawings, with eight pairs ofmolds-that is, sixteen in all. Each pair of molds can be removed easilyand separately, being constructed as shown in Figs. 8 and 9. They areheld togetherby bolts a, and when in position the bolts 1) keep them intheir place.

0 0 represent the bottom plungers, which are each terminated by a roller0 to work on the central cam D.

d are the slides for the bottom plungers. These slides are adjusted byset-pins e, acting on plates f.

E is the hopper, through which the molds are filled with material asthey pass beneath it. The exact quantity is adjusted by means of a leverh, (or similar contrivance,) mounted on a pin 9, fixed to the frame Fand operated by a rod h and hand-wheel z", screwing on the upper end ofsaid rod, the said rod h and hand-wheel t' being arranged in bearings 7111 on the hopper E. This regulates the depth that the bottom plungerfalls as it passes the hopper E by the roller-spindle 0' coming onto thelever h, and so preventing the roller 0 from reaching the cam to anextent depending on the operation of the handwheel 2'.

G is a rocking lever pivoted to the frame F and connected by rod G tothe pusher G Such lever is worked by projections jj, Fig. 7, on thecylinder-frame, thus causing the pusher G to push off the bricks as theyare finished.

H H are segments which carry the crossheads K and toggle-levers Z and inwhich are formed the slides for the top plungers I. The toggle-leversZare worked by the eccentrics J J and arms m through levers an andconnecting-rods 0. The eccentrics J J are set at the correct angle toeach other and fastened to a shaft 1), which passes through the centralcam D, taking its bearings in the frame F and having also outsidebearings q. These eccentrics are driven at the correct speed and in theright direction in relation to the cylinder (in this case four to one inthe opposite direction) by outside gearing M M M M the wheel M beingfixed on the shaft 1), the wheels M M on the shaft a1, and the wheel Mon the driving-shaft y. The segments take their bearings on the edge ofthe cylinder and are tied to the center of the machine bystraps 70, asshown in Fig. 7. The segments H H are counterbalanced by weights II II(see Fig. 7,) so that the segment H is a little heavier than its weightII and always tends to fall, and H is a little lighter than its weightII and always tends to rise. The segment II at the commencement of itsstroke is resting on one of the springcatches L, arranged in theperiphery of the cylinder (see Figs. 1, 16, and 17) by means of stop aon segment-frame. As the cylinder revolves, therefore, the segment goeswith it. Meanwhile the eccentrics are acting and the plungers do theirwork. hen the end of the stroke is reached, the stud s on the eccentricgear-wheel M comes in contact with springcatch t on eccentric-arm andcarries the segment back to its original position at a speed of fourtimes that of the cylinder. Then the short arm t of the crank-lever 2525 connected with the catch 25, meets a stud a on the frame, and thecrank-lever is thereby moved, so as to release the catch 25 from thestud 3, while the segment-stop 0* has pressed down and passed over thenext cylinder-catch L and now rests on it ready to commence its nextstroke. The segment H is operated in ex actly the same way.

The cylinder A is rotated in the direction of the arrows by means ofgearing A A A A the wheel A being fixed to or forming part of thecylinder, the wheels A A being fixed on the shaft .2, and the wheel Abeing fixed on the shaft 00.

Fig. 3 represents diagrammatically an elevation of the machine, showingthe relative positions of the various parts in their first position, inwhich the molds 1 2, having been charged as they passed under the hopperE, are just ready to receive the top plungers I. The molds 3 and l havereceived their first pressure and 4 has just been pushed out to receivethe second pressure. The molds 5 and 6 are receiving their secondpressure and the molds 7 and 8 are finished. The bricks are just beingdelivered from the molds 8. In Fig. 4 the cylinder has traveledthree-fortieths of a revolution in the direction of the arrows and theeccentrics three-tenths in the opposite direction. Molds l and 2 havecommenced to receive their first pressure, 3 and 4: are ready to receivetheir second pressure, 3 having now also been pushed out, 5 and 6 arenow finished, and the segment H is just at the end of its travel(indicated by the double arrow) ready to be taken back by the eccentricsspur-wheel M, 7 is just having its completed brick pushed out to deliverit, and 8 is receiving its charge. In Fig. 5 the cylinder has traveledanother twentieth of a revolution in the direction of the arrows and theeccentric a fifth in the opposite direction. Molds l and 2 have receivedthe greater part of their pressure, 3 and 4 are just about to commencetheir second pressure, the segment II having returned, 5 and 6 arefinished, 7 is being delivered, and S has got its charge complete. InFig. 6 the cylinder has traveled another three-fortieths of a revolutionin the direction of the arrows and the eccentrics three-tenths in theopposite direction. Molds 1 and 2 have received their first pressure andthe segment H has reached the end of its travel, as indicated by thedouble arrow, and is about to return, 3 and 4 are receiving their secondpressure, 5 and 6 are finished, the bottom plunger of 6 is just risingto deliver, 7 is-charging, and 8is ready for its first pressure. Thiscompletes the cycle as Fig. 3 shows the cylinder after traveling anothertwentieth of a revolution, and by putting 7 and 8 in the place ofl and 2and so on itwill give the correct positions of the various parts again.
